Why doesn't Gentoo work with -march=native in Alder-Lake CPUs when -march=alderlake does work (lemm.ee)

it appears to be a known issue because when I was searching for the cache size being different it was the first thing that popped up but I'm trying to understand why they aren't equivalent to emerge.

To see what gcc picks up for your -march=native, run resolve-march-native --keep-mno-flags. Available as app-misc/resolve-march-native.
